Reversible and reproducible giant universal electroresistance effect
20 Nov 2013 | Contributor(s):: syed rizwan hussain naqvi
After the prediction of the giant electroresistance effect, much work has been carried out to find this effect in practical devices. We demonstrate a novel way to obtain a large electroresistance (ER) effect in the multilayer system at room temperature. The current-in-plane (CIP) electric...
Exchange-bias like hysteretic magnetoelectric-coupling of as-grown synthetic antiferromagnetic structures
The magnetoelectric (ME) coupling of CoFeB/Ru/CoFeB synthetic antiferromagnetic (SAF) structure is studied at room-temperature when the SAF structure was deposited on the (011)-Pb(Mg1/3Nb2/3)O3-PbTiO3 piezoelectric substrate. It was found that the magnetoelectric coupling showed butterfly like...

Evolution of microstructure and magnetic properties in magnetron-sputtered CoCr thin films
02 Feb 2012 | | Contributor(s):: Brian Demczyk
In this work, transmission electron microscopy, including the Lorentz mode is combined with magnetic measurements (vibrating sample magnetometry and ferromagnetic resonance)to draw correlations between the structural and magnetic constituents in cobalt-chromium films of increasing thickness.
Performance of Magnetic Quantum Cellular Automata and Limitations due to Thermal Noise
02 Jun 2011 | | Contributor(s):: Ajey Jacob, Dmitri Nikonov
Operation parameters of magnetic quantum cellular automata are evaluated for the purposes ofreliable logic operation. The dynamics if nanomagnets is simulated via Landau-Lifshitz-Gilbert equations with stochastic magnetic field corresponding to thermal fluctuations. It is found that in the...
